Users Guide

• Data lls up the rst disk before it is written to the second disk.
• No redundant data is stored. When a disk fails, the large virtual disk fails.
• No performance gain.
• No redundancy.
RAID level 0 - striping
RAID 0 uses data striping, which is writing data in equal-sized segments across the physical disks. RAID 0 does not provide data
redundancy.
RAID 0 characteristics:
• Groups n disks as one large virtual disk with a capacity of (smallest disk size) *n disks.
• Data is stored to the disks alternately.
• No redundant data is stored. When a disk fails, the large virtual disk fails with no means of rebuilding the data.
• Better read and write performance.
RAID level 1 - mirroring
RAID 1 is the simplest form of maintaining redundant data. In RAID 1, data is mirrored or duplicated on one or more physical disks. If a
physical disk fails, data can be rebuilt using the data from the other side of the mirror.
